The WG is chasing Robin for 20 years. If they would have had a clue where she was they would have taken her. I´m sure that no matter in what organisation she has worked before BW, nobody in the WG would know that she was a part of it. If they would have known, they would have come to take all of them down.
How did they find out that she was part of those organisations you may ask. Easy. They found probably out the same way they found out about BW. The organisations were destroyed and then they began to investigate who was part of it. That´s the only logic way how they could have found out. Because as I stated above, if they would have known that Robin was there while these organisations were still intact, they would have come to take her.
You'r not getting my point. They knew robin has been in criminal orginizations since she was eight. I know how they found out she was in them. My point is up until now, Robin being a part of the mugiwaras is no different from her being in any of the other varius orginizations. They don't know robin has sprouted feelings for this group. So they think or thought that she will do to them what she did to the other varius orginizations she was in, betray them.
I don´t understand where the idea that Luffy isn´t been taken serious is coming from. Of course random people don´t know why Luffy got this high bounty because if the WG would tell the truth, then the whole world would know how incompetent they are and that Luffy did a good thing. Telling the truth would mean that they are shooting themselves in the knee. So they just raise Luffy´s bounty and let everyone else clueless about what Luffy really did.
**I agree with the part about why they didn't tell the world. Like you said, it would only hurt them.
The gouresi take Luffy seriuosl, too an extent. Hence my usage of the word too.**
The WG itself does take him seriously. In chapter 233 the Gorousei themselves said:"And now the man who defeated him… We cannot allow him to run free either... Monkey D. Luffy...".
And then we see Ao-kiji.
Aokiji: The governments aren't taking you all too seriously yet…
But when you get down to the grit, you've got a tough crew here.
Even with your small number,
given the kind of manpower we're dealing with,
you're going to be a big problem, in the future.
That doesn´t sound like a statement that indicates that they don´t take him serious. The Strawhats are even on the agenda of the meeting in Maryjoa. If he wouldn´t be taken serious then he wouldn´t be on the agenda of a meeting where the head of the Marine and three Shichibukai if they are present.
I was always under the assumption that the meeting was more about replacing crocodile than Luffy and Zoro. I always though they were a minor matter at the meeting. I thought the luffy and zoro part of the meeting was trying to make sure the seceret about who really defeated croc wouldn not leak. I could be wrong, but this is how I see it.
Sorry, but that entire he´s not taken seriously thing is a bunch of crap because these chapters 233 and 234 show that the WG and the Marine is taking Luffy serious. They probably just don´t take them on the same level as Whitebeard but there´s no doubt that he is taken serious. Defeating a Shichibukai is a big thing.
And I already stated they don't take him too seriously. I know they take hm seriously, but not very much. Because other things are in the WGs way besides them.
Oh and before anybody throws the question in why we didn´t see Luffy been taken seriously by the WG after the Maryjoa meeting. The one and only Marine we saw meeting the Strawhats was Aokiji and he beat up Luffy and let him go afterwards because he owed him one. And the other allied people to the WG are CP9. And Lucci and the others had to let him go because it was a deal and Spandam of course doesn´t take him seriously because he´s a complete moron that only understands things when it is too late.
CP9 ( excluding Spandam) were completley confident even though he is worth 100 million. Luffy as you know id worth a more then his current bounty. Esp since crocs former bounty is only 1/3 of what his bounty would've been if he was a regular pirate.
There never was any time to show how Luffy was taken seriously be the WG. In Skypiea there was neither the Marine nor the WG, at Longring Longland there was the Aokiji thing and at Water 7/Enies Lobby there´s the CP9 thing.
There were not many times to show how seriously he was taken, thats true. But the raid on Enies lobby is a perfect example of how seriously they take him.
